Logan producer Simon Kinberg hints that there is a very strong chance that Minister Sinister might appear in the next X-Men movie, or one of its latest screen incarnations. One of the most powerful mutant villains in X-Men lore, teases about his existence and emergence have come out in two recent movies: X-Men: Age of Apocalypse and Logan.
Spoiler jump now for those who don't want to know anything about the soon-to-open Wolverine movie.
In one bloody aftermath of Logan's fight against the bad guys running after him, Laura, and Professor X, a clean-up squad tidies up the place and removes all traces of the carnage. One of them takes out a vial of blood with the tag "Weapon X" and places it inside a briefcase that has the label ESSEX CORP.
ESSEX CORP, which is Sinister's company in the comics, has also been referenced in the post-credit scene of X-Men: Age of Apocalypse. The two are very similar. Again, another techie-looking agent scans the area where Wolverine had another nasty brawl with the government people out to capture Professor X's students. The agent places a vial of blood titled "Weapon-X" and places it inside a briefcase also labeled ESSEX CORP.
Those are two strong hints about Essex Corp. existing in the X-Men cinematic universe. Nathaniel Essex or Minister Sinister uses the company as his front to accelerate the evolution of mutant-kind by whatever means necessary. He is sympathetic neither to Charles Xavier's call for mutual co-existence with humans, or Magneto's campaign to win the war against them.
Cinema Blend asked Kinberg about the possibility of Sinister appearing in an X-Men movie in the future. The producer of X-Men: Days of Future Past gave an enthusiastic answer:
"The short answer is yes. We would love to see Sinister. I think he is one of the great untapped villains in the X-Men universe, and we do have plans to introduce him into the world."
Now this is not an idle claim by a mutant-fan-turned-movie producer. Kinberg is in the middle of the X-Men cinematic juggernaut: IMDB racks up his creds as the current producer of the TV series Legion which focuses on a supposed son of Charles Xavier; the executive producer of a still untitled X-Men TV series; and the producer of two upcoming movies, Gambit and X-Men: The New Mutants.
Kinberg has the power, the connections, and the creativity to bring Sinister front and center into the X-Men franchise. After Apocalypse's lackluster showing, the series does need a strong villain who can go against Magneto and Xavier alike. That was one reason why Marvel created him in the comic books: to introduce new fresh villainy blood. With Kinberg at the helm, that same strategy can happen in the movies.
One thing that the X-Men franchise has that keeps it perpetually new is the revolving cast of characters who they can bring back from previous movies (e.g. Beast), develop from the comics, or invent from zero.
Here's of those clips announcing Sinister's appearance:
Logan, starring Hugh Jackman, directed by James Mangold, and produced by Simon Kinberg, will open at the movie houses on March 3, 2017.
